List of source folders on build path [message #111557]

Given an IJavaProject, how do I programatically get a list of all source
folders on build path?
I am able to get the output folder by using getOutputLocation() but I can't
seem to find anything in the API docs to get the source folders.
Thanks

Vijay

IJavaProject javaProject = ...;
ArrayList sourceFolders = new ArrayList();
IWorkspaceRoot root = ResourcesPlugin.getWorkspace().getRoot();
IClasspathEntry[] entries = javaProject..getResolvedClasspath(true);
for (int i = 0; i < entries.length; i++) {
IClasspathEntry entry = entries[i];
if (entry.getEntryKind() == IClasspathEntry.CPE_SOURCE) {
IPath path = entry.getPath();
IFolder sourceFolder = root.getFolder(path);
sourceFolders.add(sourceFolder);
}
}

Jerome,
This works except for this situation:
I created a project called "djsk" and added some files (in the default
package) without creating a source folder. The source folder on build path
is djsk
Now I get the following exception:
java.lang.IllegalArgumentException: Path must include project and resource
name: /djsk
on the call:
IFolder sourceFolder = root.getFolder(path);

Looks like I *have* to create folders in the project to put my source?

Thanks
Vijay

No, you just need to check if the IPath has only 1 segment. In this case use
getProject(...) instead of getFolder(...).
